BAPTISM -BRULE WATERSHED (MN) HUC: 04010101 Rapid Watershed Assessment Baptism-Brule (MN) HUC: 04010101 Rapid watershed assessments provide initial estimates of where conservation investments would best address the concerns of landowners, conservation districts, and other community organizations and stakeholders. These assessments help land–owners and local leaders set priorities and determine the best actions to achieve their goals.

BAPTISM -BRULE WATERSHED (MN) HUC: 04010101 Introduction The Baptism Brule 8-Digit Hydrologic Unit Code (HUC) subbasin is located in the Northern Lakes and Forest ecoregion of Minnesota. This largely forested watershed is 1,019,923 acres in size. Approximately fourteen percent of the land in this HUC is privately owned, and the remainder is tribal, state, county, conservancy or federally owned land. Assessment estimates indicate 22 farms located in the watershed. Approximately eighty two percent of the operations are less than 180 acres in size, eighteen percent are from 180 to 1000 acres in size, and no farms in this HUC appear to be greater than 1000 acres. Of the 20 operators in the watershed, 47 percent are full-time producers not reliant on off-farm income. The main resource concerns throughout the watershed are sheet and rill, streambank, lakeshore and roadside erosion, groundwater quality and quantity, surfacewater quality and quantity, timberland management, shoreline management, and wetland management. Associated with the erosion runoff and stormwater issues are increased sediment and pollutant loadings to surface waters.

This watershed is home to Eagle Mountian, the highest point in Minnesota at 2,301 feet above msl. Interestingly, this highest point is 15 miles from Minnesota’s Lowest elevation, Lake Superior, at 607 ft above msl. Precipitation in the watershed ranges from 27 to 33 inches annually. Evaporation estimates are between 28 to 32 inches annually (Minnesota State Climatologists Office, 1999). Much of the land within this HUC is not considered Average Precipitation highly erodible, and is poorly suited to agricultural uses. Predominate land uses / land covers are Forest (85.9%), Open Water (6.5%), Shrub/Scrubland (3.4%), and Wetlands (3.0%) Land use within the watershed is scarcely agricultural, accounting for less than one percent of the available acres. Development pressure is moderate, with some timberland, resorts and lakeshore being parceled out for recreation, lake or country homes.

Slightly more than fifty seven percent of the land in the watershed is Federally owned ( 582,694 acres). The second largest ownership type is State, with approximately 221,980 acres (21.8%), followed by Private with 146,979 acres (14.4%), Tribal with 43,499 acres (4.3%), Private major with 21,504 acres (2.1%), and Conservancy with 2,316 acres (0.2%). County lands account for the smallest ownership percentage, occupying 954 acres (0.1%). Land use by ownership type is represented in the table below.

These standards define how much of a pollutant can be in the water and still allow it to meet designated uses, such as drinking water, fishing and swimming. The standards are set on a wide range of pollutants, including bacteria, nutrients, turbidity and mercury. A water body is “impaired” if it fails to meet one or more water quality standards. To identify and restore impaired waters, Section 303(d) of the Clean Water Act requires the Minnesota Pollution Control Agency (MPCA) to: • Assess all waters of the state to determine if they meet water-quality standards • List waters that do not meet standards (the 303d List) and update every other year • Conduct TMDL studies in order to set pollutant reduction goals needed to restore waters. Federal and state regulations and programs also require implementation of restoration measures to meet TMDLs. MPCA responsibilities include performing assessment activities, listing impaired waters, and conducting TMDLs in Minnesota. The agency also coordinates closely with other state and local agencies on restoration activities. The Total Maximum Daily Load (TMDL) list is updated every two years (the next list will be approved in 2008). Following assessment of water quality data and an extensive public participation process, the draft TMDL list is submitted to the U.S. EPA for final approval. 2006 Minnesota 303d Listed Streams - Baptism-Brule Listed Stream Impairment Affected Use Pigeon River South Fowl Lk to Pigeon Bay Mercury Aquatic Consumption Brule River Greenwood R to Lk Superior Mercury Aquatic Consumption Poplar River Superior Hiking Trail bridge to Lk Superior Mercury, Turbidity Aquatic Consumption
